As previously posted, Fidelity Netbenefits is unable to be used within Quicken since their "migration". Is this ever going to be fixed?
Unable to log into Fidelity Netbenefits after Migration — Quicken
Entirely, and solely, Fidelity's choice. Bug them to make this happen.
Q can't make this happen because it requires changes on Fidelity's end.
It works for me. Choose Fidelity Investments as the Financial institution when adding the account.
@cyberphile So it would seem that you also have other accounts at Fidelity.
As reported, WAAAY down, in the link in the OP, that doesn't work if you have ONLY NetBenefits.
Fidelity bug for not presenting it.
